Method and system for controlling lighting based on influence of lighting

Abstract

A method of controlling lighting based on influence of the lighting may include: classifying a predetermined area including a plurality of lightings into a plurality of sub-areas; calculating a detailed influence of each of the plurality of lightings on each of the plurality of sub-areas; determining an influence of each of the plurality of lightings on the predetermined area by using a sum of the calculated, detailed influences on the plurality of respective sub-areas; determining ranking of influence of the plurality of lightings, based on each of the determined influences of the plurality of respective lightings; and controlling the plurality of lightings based on the determined ranking of influence of the plurality of lightings.

What is claimed is: 
     
       1. A method of controlling lighting based on influence of the lighting, the method performed by at least one processor, the method comprising:
 classifying a predetermined area comprising a plurality of lightings into a plurality of sub-areas; 
 calculating a detailed influence of each of the plurality of lightings relative to each of the plurality of sub-areas; 
 determining an influence of each of the plurality of lightings relative to the predetermined area by using a sum of the calculated, detailed influences; 
 determining a ranking of influences associated with each of the plurality of lightings, based on each of the determined influences; and 
 controlling the plurality of lightings based on the determined ranking of influences such that, when lowering an illuminance of the predetermined area, the controlling comprises adjusting each of the plurality of lightings in an ascending order according to the determined ranking of influences. 
 
     
     
       2. The method of  claim 1 , wherein calculating the detailed influence further comprises:
 determining a vertical illuminance value for each of the plurality of lightings; 
 determining an illuminance value according to a distance between each of the plurality of lightings and each of the plurality of sub-areas; and 
 calculating the detailed influence of each of the plurality of lightings relative to each of the plurality of sub-areas by using a ratio of the illuminance value to the vertical illuminance value. 
 
     
     
       3. The method of  claim 1 , wherein controlling of the plurality of lightings further comprises:
 when increasing an illuminance of the predetermined area, adjusting each of the plurality of lightings in a descending order according to the determined ranking of influences. 
 
     
     
       4. The method of  claim 1 , further comprising:
 calculating a natural light score based on influence of a natural light on illuminance on the predetermined area, 
 wherein controlling the plurality of lightings further comprises: 
 controlling the plurality of lightings such that an illuminance value associated with the predetermined area is constantly maintained based on the calculated natural light score. 
 
     
     
       5. The method of  claim 1 , wherein determining the ranking of influences further comprises:
 ranking an influence associated with the predetermined area; and 
 ranking the influences associated with each of the plurality of sub-areas. 
 
     
     
       6. A non-transitory computer-readable recording medium storing instructions for execution by one or more processors that, when executed by the one or more processors, cause the one or more processors to perform the method according to  claim 1 . 
     
     
       7. A lighting control system comprising:
 a communication module; 
 a memory; and 
 at least one processor connected to the memory and configured to execute at least one computer-readable program included in the memory, 
 wherein the at least one program comprises instructions to: 
 classify a predetermined area comprising a plurality of lightings into a plurality of sub-areas; 
 calculate a detailed influence of each of the plurality of lightings relative to each of the plurality of sub-areas; 
 determine an influence of each of the plurality of lightings relative to the predetermined area by using a sum of the calculated, detailed influences; 
 determine a ranking of influences associated with each of the plurality of lightings, based on each of the determined influences; and 
 control the plurality of lightings based on the determined ranking of influences such that, when increasing an illuminance of the predetermined area, the instruction to control further comprises an instruction to adjust each of the plurality of lightings in a descending order according to the determined ranking of influences.
